We look at the division of 56402844 by 456 
The aim is to understand the frequency of 456 in 56402844.

Let's proceed to step 1:
456 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 456

Going ahead to step 2:
56 divided by 456 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 456

On to step 3:
456 can be fit into 564 1 times, resulting in a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 108 after subtracting 456 from 564.
Fetch the next digit (0) from the dividend, attach it to 108 and continue: 1080 / 456

Let's proceed to step 4:
If we divide 1080 by 456, we get 2 and a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 912 from 1080 leaves us with 168.
Grab the next digit (2) from the dividend, add it to 168, then carry on: 1682 / 456

On to step 5:
The number 456 fits into 1682 3 times, leaving a remainder of 314.
Use 3 as the next digit of our solution. 
Result so far: 123.0
The remainder is 314 after subtracting 1368 from 1682.
Bring next digit (8) of the dividend behind the 314 and repeat the process: 3148 / 456

On to step 6:
If we divide 3148 by 456, we get 6 and a remainder of 412.
The next digit of our result is 6. 
Result so far: 1236.0
The remainder is 412 after subtracting 2736 from 3148.
Grab the next digit (4) from the dividend, add it to 412, then carry on: 4124 / 456

On to step 7:
4124 divided by 456 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 12369.0
Deduct 4104 from 4124 and we're left with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 456

Moving on to step 8:
The number 456 fits into 204 0 times, leaving a remainder of 204.
Put 0 as the next digit of the answer. 
Result so far: 123690.0
The remainder is 204 after subtracting 0 from 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 9:
456 goes into 2040 4 times with a remainder of 216.
The number 4 becomes the next digit in our result. 
Result so far: 123690.4
Subtracting 1824 from 2040 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 10:
The number 456 fits into 2160 4 times, leaving a remainder of 336.
Put 4 as the next digit of the answer. 
Result so far: 123690.44
If we take 1824 away from 2160, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Our division results in 123690.44 with a remaining 0.336.
